WINDOW.

Specification of Letters Patent.

Patented Nov. 19, 1918.

Application filed April 5, 1918. Serial No. 226,803.

, new and useful Improvements in Windows,

of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

My invention relates to what is known as pocket windows in which a pocket is provided in the upper portion of the sash frame for the reception of the sash to give a free and unobstructed window opening. It is usual in pocket windows of the kind specified to also provide for window screens which are located outside the sash and adapted to be also pushed up into the window pocket to obtain free access to the sash, or for winter storage.

In the installation of pocket windows, it sometimes happens in certain portions of the building that there is not sufiicient room above the window opening for a pocket ofproper depth to receive the entire window sashes and screens. But in such installation,

it is the desire that all of the windows for the entir building shall be alike.

It is the o'bj ect, therefore, of my invention to provide a construction in which while provision is made for the use of window screens, the screens may be removed or not used at all, and in the event that the screens are removed provision shall be made for effectively closing the opening which ordinarily would be left, and thus to render the construction airtight and effective, regardless of the use or removal of the screens.

This object I accomplish by that certain novel construction and arrangement of parts to be hereinafter specifically pointed out and claimed.

In the drawing,

Figure 1 is a vertical longitudinal section of my improved window construction.

Fig. 2 is a detail perspective of one upper corner of the window opening at the entrance to the pocket, illustrating my improvement in position when the screens are in use.

Fig. 3 is a similar view when the screens are removed.

The pocket window is provided with the usual lower and upper sliding sashes 1, 2, with the meeting rails 3, 4, the sashes being mounted in the side stiles 5, 6, with the inside and outside beads 7, 8, and the parting bead 9, with the sill 10 and headpiece 11. The stiles run to the top of the pocket above the inner opening and the headpiece incloses the pocket top, while the front of the pocket is, in the construction illustrated, formed of corrugated sheet metal 12, suitable for plastering, and the outer wall of the pocket is inclosed by sheeting 14 over which the weatherboarding 15 for the outside structure in frame buildings is secured. The window casing is also provided with the usual inside and outsid frames 16, 17, and the sashes are provided with the usual sash cords 18, which run over the sash pulleys 19, 19, at the head of the stiles, the sash cords being attached to the usual weights in the weight box behind the stiles.

Outside of the sash stiles is the usual channel strip 20, on each side, to serve as a guide for the window screen. These screens are preferably formed of metal frames, 21 for the lower and 22 for the upper screens, with wire screening 23 secured in the frames in any suitable way. As illustrated in the drawing, a flange strip is provided for the top rail of the lower screen to engage over the lower rail of the upper screen to form a close join-t, while the upper rail of the upper screen is formed of double thickness to fill out the opening in the guideway. For holding the screens up in the pocket, I provide the spring plates or strips 24 which are riveted or otherwise secured in the screen runways, so that the plates can spring out to hold up the screens when they are raised beyond the ends of the plates, adapted to be pressed in to allow the screens to be lowered.

Secured to the underedge of the sheeting at the upper edge of the window opening is the Weatherstrip 25, provided with a strip of suitable Weatherstrip material 26, which 1 cars against the outer surfacev of the uppe' rail of the upper screen 22 when the screens are in place, while tne weatherstrip secured on the upper rail of the upper sash bears against the inner surface of the upper screen.

To effectively close this opening, which would be left when the screens are removed in the winter time, either because of the lack of depth to the pocket, or when for any reason screens not desired, 1 hinge to the under side of the Weatherstrip 25 a strip 28 by the hinges 29. This strip is provided at its end with a sliding bolt 30, to lock the strip in the position shown in Fig. 2, so that the screens can be freelv raised and lowered. in order to inclose and protect the "Weatherstrip material 26 when the screens are removed and the hinge strip is folded up into the position shown in Fig. 3, I provide the longitudinal groove 31, which is of suliicient width and depth to fully protectthe Weatherstrip. The thickness of the hinge strip 28 is the same as the thickness of the upper rail of the upper screen, so that when the hinge strip 28 is folded up, the Weatherstrip on the sash bears agaii'ist the strip to form a weathertight joint. d hen the strip is thus folded up, the sliding bolt fits within the guide channel for the screens, locking the strip in position.

The cross sectional shape of the hinged strip 28 practically corresponds to the shape of the upper rail of the window screen, so that when the screen is removed, the strip can take. its place, serving as a hearing for the s eh rail weatherstrip on one side and providing a groove to receive and inclose the Weatherstrip on the outside. Thus a perfect weatherproof closure is obtained whether the screens are used or not. Moreover every detail of the pocket window construction can he the same, whether there room for the pocket window of full depth or not, except that the pockets may not be of the same depth.

l-laving thus described my invention, what- 1 claim as new and desire to secure by Letters Patent, is 1 1. in a pocket window, tile combination a window frame and wall pocket with sashes and screens to slide into the pocket, of a closure member located at the mouth of the pocket mounted on the frame and adapted to close the screen opening when the screens are removed.

2. in a pocket window, the combination of a window frame and wall pocket with sashes and screens to slide into the pocket. of a closure member located at the mouth of the pocket hinged on the frame and adapted to swing into place to close the screen openwhen the screens are removed.

3. ln a pocket window, the combination of a window frame and wall pocket with sa hes and screens to slide into the pocket, of a molding secured along the mouth of said pocket, and a supplemental strip hinged to the molding, and adapted to close the screen opening when the screens are removed.

i. In a pocket window, the combination of a Window frame and wall pocket with sashes and screens to slide into the pocket, of molding secured along the mouth of said pocket, having Weatherstrip material secured thereto to contact with the screen frame, to form a weather-tight closure, when the screens are mounted in the Window frame, and a supplemental strip hinged to the molding, and adapted to close the opening, and to protect the said Weatherstrip material. when the screens areremoved.
